WebThe number of hydrogen bonds is higher, the hydrogen bonding strength is greater and the water solubility is also high. Among all the four chemical compound ethylene glycol(OH – CH2 – CH2 – OH) has two hydroxyl group and both are available for hydrogen bonding with water. As a result water solubility of ethylene glycol is high. WebSolubilities of ethylene at atmospheric pressure and temperatures ranging from −9°C to 70°C are reported in solvents ranging from the non-polar ones, heptane, dodecane, carbon …
